3494751FIELD OF INVENTION[0001] The present disclosure relates to a casing system for windows or doors and a method for mounting the casing system.5 BACKGROUND[0002] Windows and doors are commonly installed in walls of buildings. Installing a window or a door in a wall of a building typically involves first installing a frame in which a window pane(s) or door is mounted and then installing a casing to cover gaps between the window or door frame and the surrounding wall structure. Casings provide both 10 functional and aesthetic benefits, serving to seal the installation while creating an attractive finished appearance.[0003] Wall structures vary considerably in their construction and dimensions.Scandinavian buildings in particular feature walls with varying thicknesses, and some may include surfaces that may not be perfectly straight. This may be particularly true for older 15 buildings.[0004] As a result, fitting traditional casing systems has been a challenge for those who are not professionals. Traditional casing systems are fitted by precise measurements and custom cutting to fit specific wall dimensions. Installation typically involves multiple steps of measuring, cutting, and adjusting to achieve proper alignment with wall surfaces.20 The process demands specialized tools and skills to ensure accurate fitting, as may be possessed by a skilled professional.[0005] US 4811533 describes a window trimming construction including a trim portion dimensioned and arranged to cover a portion of a surface of a wall in a position circumscribing a window opening extending through the wall that is defined by a window 25 framing. The window trimming construction also includes a molding portion dimensioned and arranged to cover a portion of the window framing disposed intermediate the surface of the wall and a metal frame mounted on the window framing. The molding portion is arranged to enable adjustment of its width according to an amount by which the metal 3494752frame is recessed. One embodiment includes a molding portion having a plurality of sections that each cover a corresponding plurality of sections of the window framing, each one of the molding sections having first and second strips joined together with an adjustable joint that enables adjustment of the width.5 [0006] CN 203822052 U describes a width-adjustable assembly-type door pocket frame. The width-adjustable assembly-type door pocket frame comprises a main frame body and an auxiliary frame body which can be assembled with the main frame body. An auxiliary frame body fixing groove is formed in one side of the main frame body, and an inserting head which is adaptive to the auxiliary frame body fixing groove is formed on 10 one side of the auxiliary frame body. The width-adjustable assembly-type door pocket frame is characterized in that a U-shaped connecting piece is fixed in the auxiliary frame body fixing groove, the opening direction of the U-shaped connecting piece is the same as the opening direction of the auxiliary frame body fixing groove, a concave-convex structure is formed at the inner edge of the side, against a wall, of the U-shaped connecting 15 piece, an adjusting connecting piece is fixed to the outer edge of the side, against the wall, of the inserting head and a convex-concave structure which can be matched with the concave-convex structure is formed at the outer edge of the side, against the wall, of the adjusting connecting piece.[0007] CN 217925470 U describes a novel sealing adjustable integrated dry paint 20 wooden door wrapping opening which comprises an A opening plate symmetry, a B opening plate symmetry, an anti-collision rubber strip and an opening line, the opening line comprises a plate body, an adjusting hole is formed in the plate body, and an adjusting insertion plate is connected to the left side of an adjusting screw in a clamped mode.According to the novel sealing adjustable integrated dry paint wooden door wrapping 25 opening, the A connecting inserting groove and the left connecting inserting groove are connected in an inserted mode, the A opening plate is symmetrically connected with the B opening plate, meanwhile, the plate body is inserted into the right connecting inserting groove, the B opening plate is symmetrically connected with the opening line, installation is convenient, and due to the fact that the anti-collision inserting groove in the B opening 30 plate is located below the left connecting inserting groove, the anti-collision effect is good. 3494753[0008] For those attempting to improve their own homes, however, there are significant challenges and traditional casing systems present difficulties. As a result, it is commonly the case that casings are improperly installed, resulting in visible gaps, misalignment with wall surfaces, or inadequate sealing around the window or door frame.5 When wall surfaces are uneven or not perfectly straight, achieving flush alignment between the casing and wall surface becomes particularly challenging. Poor alignment can create aesthetic issues. Accordingly, there is a desire to provide a casing system that enables proper installation by all.SUMMARY10 [0009] According to a first aspect, there is provided a casing system for mounting in a casing groove in a frame for a window or a door. The casing system comprises a first casing with a fastening side that fits into the casing groove, a second casing telescopically cooperating with the first casing in a direction parallel with a centerline of the frame, and an adjustment system to regulate and lock a distance between the second casing and the 15 fastening side of the first casing. The adjustment system comprises one of: A locking list having a sticking substance applied on two attachment sides wherein one of the two attachment sides sticks to an outer side of the first casing and the other of the two attachments sides tick to a side surface of the second casing facing the first casing, or a plurality of adjustment units distributed around the circumference of the two telescopically 20 interacting first and second casing.[0010] This configuration allows for easy installation and precise adjustment of the casing to accommodate varying wall thicknesses and skewed surfaces, while maintaining a secure fit within the frame. Accordingly, the need to cut the casing to size is reduced, and also reduces the effort required to fit a casing to a particular wall. This provides a more 25 efficient construction process and reduces waste.[0011] The telescopic arrangement of the two casings allows for one casing to be securely positioned within the other, thereby resulting in a smaller volume than an entire casing system alone. This can reduce the risk of damage during transport and/or storage and can minimize the need for extra packing. Further reductions of damage may be 3494754achieved because such a system can be provided as a flat pack, thereby further reducing the volume of the materials during transport.[0012] The ease of fitting the casing system described above may also reduce the risk of workplace accidents on construction sites. Traditionally, installing wooden5 casings/linings requires the use of table saws or circular saws. With this casing system, the need for such tools is eliminated, reducing the risk of cuts. Additionally, there is less noise and dust during installation, which improves the working environment for craftsmen.[0013] The adjustable nature of the casing system also allows for straightforward remodelling or adaptations should wall thicknesses be altered or if different arrangements 10 are desired. In some examples, the window/door frame and casing system may remain in place, with adjustments being made between the components.[0014] The second casing may telescopically cooperate with the first casing by an outer surface of the second casing being in contact with or sliding within an inner surface of the first casing. Alternatively, the second casing may telescopically cooperate by having 15 an inner surface that is in contact with an outer surface of the first casing. In yet a further alternative, the second casing may telescopically cooperate with the first casing by means of a groove formed within the first casing. The outer surfaces may be referred to as wallfacing or wall sides or surfaces. Obviously, the mentioned wall is the inside wall of the house.20 [0015] The adjustment system may comprise a locking list having a sticking substance applied on two attachment sides. One of the two attachment sides may stick to an outer side of the first casing and the other of the two attachments sides may stick to a side surface of the second casing facing the first casing. The sticking substance may comprise double sided tape. This arrangement provides a secure and adjustable connection between 25 the casings without requiring mechanical fasteners. The locking list may be referred to as a locking lining. The outer side may be opposite to the fastening side. The attachment sides may therefore be perpendicular to one another. Preferably, one locking list is positioned on each of four sides of the casing system. 3494755[0016] The adjustment system may comprise a plurality of adjustment units distributed around the circumference of the two telescopically interacting first and second casing.[0017] Each adjustment unit may comprise a nut attached to one of the first and 5 second casings and a screw adapted to the nut. The screw may be rotatably attached to the other of the first and second casing for adjusting the distance D. The locking of the distance may take place by the friction between screw and nut preventing relative movement between the first and second casing.[0018] The adjustment units may comprise a pre-drilled hole in the one of the first and 10 second casings which is closest to the centerline of the frame, and a locking screw configured to be screwed through the pre-drilled hole and into the first or second casing whichever is furthest away from the center line of the frame to position an outer wall alignment surface of a wall side of the second casing flush with the wall surface.[0019] Each of four casing side sections of the first and second casing may be a 15 separate unit that can be joined together to form a complete first or second casing by means of a joining piece in each casing corner.[0020] The first and second casings may be made of wood, or a plastic material. The plastic material may be PVC. Utilizing a hard plastic such as PVC may reduce the need for acclimatization of the materials in colder climates such as in Scandinavia. Such materials 20 are also more durable, leading to a longer lifespan.[0021] According to a second aspect, there is provided a method for mounting the casing system may comprise the following steps:a. mounting the first casing in the casing groove in the frame,b. mounting the second casing to cooperate telescopically with the first casing, 25 c. adjusting the distance D between the second casing and the fastening side of the first casing, until a wall side of the second casing is flush with the wall surface in either of two ways:If the adjustment system comprises a locking list having a sticking substance applied on two attachment sides wherein one of the two 3494756attachment sides sticks to an outer side of the first casing and the other of the two attachments sides stick to a side surface of the second casing facing the first casing, then adjusting the distance D manually, orif the adjustment system comprises a plurality of adjustment units5 distributed around the circumference of the two telescopically interacting first and second casing, then adjusting the distance D by turning the screw in each adjustment unit, andd. locking the distance D using the adjustment system in either of two ways.if the adjustment system comprises a locking list having a sticking10 substance applied on two attachment sides wherein one of the two attachment sides sticks to an outer side of the first casing and the other of the two attachments sides stick to a side surface of the second casing facing the first casing, then sticking the locking list to an outer surface of the first casing and to whichever of the inner or outer side of the second casing 15 which is closest to the first casing, orif the adjustment system comprises a plurality of adjustment units distributed around the circumference of the two telescopically interacting first and second casing, then letting the friction between the screw and nut lock the distance D.20 [0022] The method may comprise applying a locking list to the first casing and to the second casing. Adjusting the distance between the second casing and the fastening side of the first casing may be performed by sliding the second casing relative to the first casing. The method may comprise fixing the casing system to a window frame.[0023] Step c. may comprise adjusting the distance D manually and step d. comprises 25 sticking a locking list to an outer surface of the first casing and to whichever of the inner or outer side of the second casing which is closest to the first casing.[0024] Step c. may comprise adjusting the distance D by turning the screw in each adjustment unit until the outer wall alignment surface of a wall side of the second casing is 3494757flush with the wall surface. Step d. may comprise allowing the friction between the screw and nut to lock the distance D.BRIEF DESCRIPTION OF FIGURES[0025] FIG. 1 shows a first embodiment of the casing system.5 [0026] FIG. 2 shows a second embodiment of the casing system.[0027] FIG. 3 shows a window assembly in which a casing system is mounted to a frame of a window.[0028] FIG. 4 shows a window assembly including a window.[0029] FIG. 5 shows a cross-section of the first casing system.10 [0030] FIG. 6 shows a close-up perspective view of an adjustment unit of the first casing system.[0031] FIG. 7 shows a cross-section of the second casing system.[0032] FI8. 9 shows a fixing mechanism for use in a casing system.[0033] FIG. 9a shows a casing having a variable size and FIG.9b shows a side of the 15 casing of FIG.19a.[0034] FIGS. 10a and 10b show different views for applying a list between the casing and a wall.[0035] FIG. 11a shows two sides of a list joined by a locking bracket and FIG.11b shows a locking bracket.20 [0036] Common reference numerals are used throughout the figures to indicate similar features.DETAILED DESCRIPTION[0037] In this text the words outward and inward relates to positions relative to the window or door frame and a centerline A, going through the window at a right angle with a 25 plane in which the frame is positioned as seen in FIG.1, where inward is closer to the frame and/or the centerline A and outward is further away. FIG.1 illustrates a first casing system 100, and FIG.2 illustrates a second casing system 200. The first casing system 100 3494758and the second casing system 200 are configured for mounting to a window frame in a wall of a building. The casing systems may occupy the gap between the window frame and surrounding wall structure to ensure a snug fit, while providing an aesthetically pleasing finished appearance and sealing the installation against air and moisture.5 [0038] The first casing system 100 and the second casing system 200 each include a first casing 1 and a second casing 2. The first casing 1 includes an inner groove contact surface 32a that faces inwardly towards frame and an outer surface 32b that faces outwardly from the frame. The second casing 2 includes an inner surface 33a that faces inwardly and an outer wall alignment surface 33b that faces outwardly. Furthermore, he 10 first casing 1 includes an inner side 1is that faces inwardly towards centerline A and an outer side 1os that faces outwardly from the centerline A. The second casing 2 includes an inner side 2is that faces inwardly towards centerline A and an outer side 2os that faces outwardly[0039] The first casing 1 and the second casing 2 are arranged so that they cooperate 15 telescopically. The second casing 2 is dimensioned to fit around the first casing 1, so that the inner side 2is of the second casing 2 is in contact with the outer side 1os of the first casing 1 and so that the first casing 1 and second casing 2 are able to move telescopically by sliding the second casing 2 over the first casing 1. Conceivably, the second casing 2 can be positioned on the inside of the first casing 1 so that the outer side 2os of the second 20 casing 2 is in contact with the inner side 1is of the first casing 1. The telescopic movement of the casings 1, 2 relative to one another enables variation of the relative positions of the casings 1, 2 and of the second casing 2 relative to a wall, allowing for precision movement to ensure a flush finish. The telescopic movement of the first casing 1 and the second casing 2 relative to one another is in a direction that is parallel with the centerline A, of the 25 casings 1, 2, and that, in use, is also a direction parallel with a centerline A of a window or door frame that the casing system 100, 200 is being used to mount.[0040] In each of the first and second casing systems 100, 200, the first casing 1 includes a fastening side 5 with the inner groove contact surface 32a configured to fit into a groove of a window frame, as will be described below in relation to FIGs.3 and 4. The 30 second casing 2 includes a wall side 21 with the outer wall alignment surface 33b configured to align with an exterior wall surface 14. Accordingly, the fastening side 5 and 3494759wall side 21 represent two ends of the casing system, and relative telescopic movement and adjustment of the casings 1, 2 can allow for correct positioning of the fastening side 5 and wall side 21 within the wall of the building.[0041] The first and second casing systems 100, 200 differ by how they can be 5 adjusted and locked to one another. Focusing now on FIG.1, the first casing system 100 includes multiple adjustment units 7 distributed around a perimeter of the system. The adjustment units 7 comprise pairs of mechanisms with one attached to the first casing 1 and one attached to the second casing 2. The mechanism may comprise a nut 8 attached to one casing and a screw-holding unit 35 attached to the other casing, and rotation of the nut 10 may cause relative movement between the casings 1, 2. A screw in each of the adjustment units is configured to adjust the casing system along adjustment axes 7a. The adjustment axes 7a are also parallel to the centerline along which the casings 1, 2 move. Preferably, the screw 9 is protected with a screw casing 34 to avoid entanglement with insulation material The adjustment units 7, as will be described in relation to Fig.5 below, allow for 15 mechanical adjustment and locking of the casings 1, 2 parallel with the centerline A.[0042] Turning to FIG.2, the second casing system 200 lacks adjustment units 7, and instead the sliding of the casings 1, 2 relative to one another may be performed manually. To lock the relative positions of the two casings 1, 2, a locking list 22 is provided, for positioning between the first casing 1 and the second casing 2, although in FIG.2 the 20 locking list 22 is shown to one side for clarity. The locking list 22 is described in more detail in relation to FIG.7 below.[0043] In each of the first and second casing systems, and other casing systems described herein, the casings may be configured for delivery as flat-pack products, with the first casing 1 and second casing 2 arranged for assembly without specialized tools. The 25 first casing 1 and the second casing 2 may be constructed from wood or a plastic material like PVC. The material selection affects the ease of cutting at the cutting sections 19 and the overall durability of the assembled frame structure.[0044] FIG. 3 illustrates a section view of a window assembly showing how a casing system comprising two telescopically sliding casings 1, 2, such as the first casing system 30 100 or the second casing system 200, mounts to a window frame 4. A casing groove 3 is 34947510formed within the window frame 4 to receive a first casing 1. The first casing 1 has a portion at its window side that extends into the casing groove 3. A window sash 27 is positioned at a lower portion of the window frame 4.[0045] FIG. 4 illustrates a front orthogonal view of a complete window assembly. The 5 window assembly may include multiple window sashes 27, a window mullion 28 that vertically separates adjacent panes, and a window transom 29 that horizontally separates upper and lower panes. The casing groove 3 extends continuously around a perimeter of the window frame 4, allowing for mounting of the first casing 1 around the entire window assembly. The window frame 4 is configured to receive either of the previously described 10 casing systems through the casing groove 3.[0046] Although windows are described in FIG.3 and 4, the casing systems described herein may also be used for mounting to door frames.[0047] FIG. 5 illustrates a section view of an adjustment system 6 for controlling relative movement between the first casing 1 and the second casing 2 of the first casing 15 system 100. The adjustment system 6 includes a plurality of adjustment units 7, only one of which is shown in FIG.5. Each adjustment unit 7 comprises a nut 8 attached to the first casing 1 and a screw 9 attached to the second casing 2 by the screw holding unit 35. The screw 9 extends through the nut 8 along the outer sides of the first and second casing 1, 2.[0048] Multiple adjustment units 7 are distributed around a circumference of the first 20 casing 1 and the second casing 2. Each adjustment unit 7 includes a corresponding nut 8 and screw 9 arrangement. Rotation of the screw 9 within the nut 8 controls the relative telescopic movement between the first casing 1 and the second casing 2, thereby adjusting a distance D between the second casing 2 and the fastening side of the first casing 1. The distance D may be adjusted to accommodate different wall thicknesses and ensure proper 25 alignment with wall surfaces. The adjustment of distance D may allow the outer wall alignment surface 33b of the wall side 21 of the second casing to be positioned flush with the wall surface while maintaining secure engagement of the fastening side within the casing groove.[0049] The friction between the screw 9 and the nut 8 locks the first casing 1 and the 30 second casing 2 at a selected position once adjusted. The screw 9 is preferably configured 34947511to be operated using a long screwdriver that will reach inside the mentioned screw casing 34, allowing for adjustment from a convenient position. The adjustment system 6 regulates and locks a distance between the first casing 1 and the second casing 2 through the coordinated operation of the multiple adjustment units 7.5 [0050] FIG. 6 illustrates a section view of the second casing 2 of the first casing system 100. FIG.6 shows a screw hole 31 in the screw casing forming part of an adjustment unit 7 on the second casing 2. In this example, the adjustment unit is integrally formed with the second casing 2. The screw hole 31 provides access for the screw 9 to engage with the nut 8. The screw 9 may be provided flush with or within the screw hole 10 31. In some examples, the screw hole 31 may also be configured to receive part of a list for enabling the screw hole 31 and the other parts of the adjustment unit 7 to be hidden from view once the casing system is mounted correctly.[0051] FIG. 7 illustrates a section view of the second casing system 200 with an adjustment system 6 installed for securing the first casing 1 to the second casing 2.15 [0052] The adjustment system 6 comprises a locking list 22 positioned between the first casing 1 and the second casing 2. The locking list 22 includes two attachment sides 25. One attachment side 25 interfaces with a side surface 24 of the second casing 2, which forms part or all of the inner surface 2is. The other attachment side 25 interfaces with an outer surface 32b of the first casing 1. The outer surface 32b is opposite to the fastening 20 surface 5. By the telescopic arrangement of the casings 1, 2, the side surface 24 and outer surface 32b are substantially perpendicular to one another, in use, and so the attachment sides 25 are also perpendicular to one another. The locking list 22 extends along a length of the first casing 1 and the second casing 2 to maintain alignment and secure attachment between the casings.25 [0053] An adhesive layer, which may be referred to as a sticking substance, 26 is applied to each of the attachment sides 25 of the locking list 22. The adhesive layer 26 comprises double-sided tape in this example, and that securely bonds the locking list 22 to both the first casing 1 and the second casing 2. The adhesive layer 26 on each attachment side 25 creates a strong bond between the locking list 22 and the respective surfaces of the 30 first casing 1 and second casing 2, preventing relative movement between the casings once 34947512positioned. As a result, the first casing 1 is also secured to the second casing 2. The double sided tape can be removed with a hobby knife if adjustment is needed due to refurbishment or repair.[0054] Prior to application of the locking list 22, the second casing 2 may be attached 5 to the first casing 1 using clips. The clips maintain initial alignment while the locking list 22 is positioned and secured using the adhesive layers 26 on the attachment sides 25.[0055] FIG. 8 illustrates a side view of an alternative fixing mechanism between a first casing 1 and a second casing 2, wherein each adjustment unit 6 comprises a predrilled hole 15 and a locking screw 16. The predrilled hole 15 is formed in whichever of the first 10 casing 1 and the second casing 2 is positioned closest to a centerline of a window or door frame. In this case, the hole is drilled in the first casing 1. A locking screw 16 is configured to pass through the predrilled hole 15 and engage with whichever of the first casing 1 and the second casing 2 is positioned furthest from the centerline, in this case the second casing 2. The locking screw 16 secures the relative positions of the first casing 1 and the second 15 casing 2.[0056] In some examples, nails or other mechanical fasteners may be passed between the first casing 1 and the second casing 2 to provide additional securing points. The mechanical fasteners may be positioned at intervals along a length of the first casing 1 and the second casing 2 to maintain alignment and prevent relative movement between the first 20 casing 1 and the second casing 2.[0057] FIGs. 9a to 11b illustrate additional features that may be employed with the casing systems described above. FIG.9a illustrates a front view of a casing, which may be used as a first casing 1 or a second casing 2 as described above. The casing shown in FIG.9a is formed from four casing side sections 18. The casing side sections 18 are joined 25 together at corners to form a complete rectangular frame structure. The cutting sections 19 enable precise length adjustment of each casing side section 18 before assembly into the complete frame structure. Each casing side section 18 forms a side of the casing.[0058] The casing side sections 18 are arranged to overlap a next casing side section 18 at one end and to be overlapped by a previous casing side section 18 at the other end. 30 When assembled, this results in overlaps at the each corner 20 that create a substantially 34947513continuous frame surface. Preferably, one end of each casing side section 18 have an end surface cut at a right angle to the longitudinal direction of the casing side section, and the other end of each casing side section 18 has a rectangular indent 36 configured to receive the end surface of an adjacent casing side section 18 that has an end surface cut at as right 5 angle as seen in fig 9a.[0059] FIG. 9b illustrates a side front view a casing side section 18. Multiple plug holes 17 for receiving corresponding casing plugs 37 are distributed along a length of the casing side section 18. The plug holes 17 are arranged in a linear pattern and extend through the casing side section 18. The plug holes 17 in the casing side sections 18 provide 10 mounting points for joining adjacent casing side sections 18. The plug holes extend along the longitudinal direction of the casing side section 18 past the cutting section 19 to enable fastening of the casing side sections when cutting off parts of the cutting section 19.[0060] FIG. 10a illustrates a section view showing an arrangement for mounting a list 12 across a second casing 2 and a wall surface 14. A plug hole 17 is formed within an 15 adjustment unit 7, which is connected to the second casing 2. The plug hole 17 receives a list plug 11 that connects to the list 12. The list plug 11 extends into the plug hole 17 to secure the list 12 to the second casing 2. The list extend across the flush outer surfaces of the wall surface 14 and the second casing 2 to enable an aesthetically pleasing covering and to cover any small gaps between the casing 2 and the wall, which may be found 20 between the adjustment units. Alternatively, the list may be fastened to the wall surface with double sided tape.[0061] FIG. 10b illustrates a side view showing the final positioning of the list 12 between the second casing 2 and the wall surface 14. The list 12 extends from the second casing 2 to meet flush with the wall surface 14, providing a finished appearance at the 25 interface between the second casing 2 and the wall surface 14.[0062] The list plug 11 and adjustment unit 7 arrangement allows for precise control over the positioning of the list 12 relative to both the second casing 2 and the wall surface 14. The plug hole 17 maintains secure engagement of the list 12 through the list plug 11 while allowing for adjustment via the adjustment unit 7 to achieve proper alignment with 30 the wall surface 14. 34947514[0063] The list 12 and list plug 11 may be used with the first casing system 100. For the second casing system 200, a list 12 may be applied using an adhesive like double sided tape or other fixing system.[0064] FIG. 11a illustrates a view of a corner section of a list 12. The list 12 includes 5 two portions arranged in an L-shaped configuration, with one portion extending vertically and another portion extending horizontally. A locking bracket 13 is depicted at a corner junction where the two portions of the list 12 meet.[0065] FIG. 11b illustrates an orthogonal view of a locking bracket 13. The locking bracket 13 comprises an L-shaped profile formed by two perpendicular sections meeting at 10 approximately 90 degrees. A vertical portion and a horizontal portion of the locking bracket 13 extend substantially perpendicular to one another. The locking bracket 13 provides structural support and maintains alignment between adjacent portions of the list 12 at corner junctions.[0066] The locking bracket 13 may be inserted into corresponding recesses formed 15 within the list 12 at corner junctions. When assembled, the locking bracket 13 maintains proper angular alignment between adjacent portions of the list 12 while providing a secure mechanical connection at corner junctions. 34947515References1 First casing1is inner side of first casing5 1os outer side of first casing2 Second casing2is inner side of second casing2os outer side of second casing3 Casing groove10 4 Window/door frame5 Fastening side6 Adjustment system7 Adjustment units8 Nut15 9 Screw11 List plug12 List/Lining13 Locking bracket14 Wall surface20 15 Predrilled hole16 Locking screw17 Plug hole18 Casing side section19 Cutting section25 20 Casing corner21 Wall side of second casing22 Locking list23 Outer side of first casing24 Attachment surface of second casing 30 25 Attachment sides of locking list 26 Double sided tape /sticking substance 27 Window sash28 Window mullion29 Window transom35 30 Sash bars31 Screw hole32a inner groove contact surface32b outer surface33a inner surface40 33b outer wall alignment surface34 Screw casing35 Screw holding unit36 Rectangular indent37 Casing plug45
